Calcium chloride can serve as a source of calcium ions in an aqueous solution, as calcium chloride is soluble in water.This property can be useful for displacing ions from solution.For example, phosphate is displaced from solution by calcium:alcium chloride can serve as a source of calcium ions in an aqueous solution, as calcium chloride is soluble in water.
People have used calciumâs compounds for thousands of years â in cement, for example. Limestone [calcium carbonate] was called calx by the Romans. The Romans heated calx, driving off carbon dioxide to leave calcium oxide.To make cement, all you have to do is mix calcium oxide with water.The Romans built vast amphitheaters and aqueducts using calcium oxide cement to bond stones together. (1). Despite the long history of calciumâs compounds, the element itself was not discovered until electricity was available for use in experiments.alcium is used to remove oxygen, sulfur and carbon from alloys. Calcium from limestone is a vital component of Portland cement. Quicklime (CaO) is used in many applications in the chemical industry, such as treatment of drinking water â especially for water softening and arsenic removal, animal waste and wastewater.
